Avon and Somerset Police are concerned for the pair's welfare as Bevan and her daughter are not dressed for the cold.

A police spokesman said: "When she [Bevan] went missing she was thought to be wearing a long black top and black trousers but was not believed to be wearing a coat. She may appear confused and worried. Her baby is inappropriately wrapped for the cold weather in a blue and white striped and coloured blankets."

Anyone who sees Bevan is asked to call 999. She is described as 5ft 8in tall, of average build, with dark wavy hair.

Officers have been searching the city centre throughout the night and appeals have been put out to bus drivers and taxi drivers and those travelling into work on early shifts this morning to lookout for Charlotte and her daughter.(Avon and Somerset Police)
